Installation Steps

  1. Disconnect Power: Unplug the recliner from the wall outlet to prevent electrical hazards.
  2. Remove Old Motor: Carefully detach the old motor. This typically involves removing four bolts that secure the motor to its bracket and detaching the solid pin with its cotter pin. You may need to cut existing cable ties to free the old cables.
  3. Position New Motor: Align the new Uetmulik motor in the correct position.
  4. Secure Motor: Attach the new motor by securing the four bolts to the bracket. Then, insert the solid pin and secure it with the cotter pin.
  5. Connect Cables: Connect the 2-pin flat round power transformer connection and the 5-pin hand control plug connection. Ensure all connections are firm and correctly seated.
  6. Organize Cables: Use small cable ties (not included) to neatly dress and secure the cables, preventing them from interfering with moving parts.
  7. Test Functionality: Once installed, plug the recliner back into the power outlet and test the motor's operation using the hand control.

Operation

The linear actuator motor facilitates the movement of your power recliner's footrest and backrest. Once properly installed and connected to the power supply and hand control, the motor will extend or retract the linear rail based on the commands from your recliner's remote or switch.

Ensure the recliner is placed on a hard, stable surface for optimal operation. Avoid placing objects that could obstruct the movement of the recliner mechanism.

Maintenance

To ensure the longevity and smooth operation of your linear actuator motor, follow these simple maintenance guidelines:

  • Cleaning: Wipe clean the motor and rail assembly with a dry or slightly damp cloth. Avoid using harsh chemicals or abrasive cleaners.
  • Connection Checks: Periodically inspect all electrical connections (power transformer and hand control plugs) to ensure they are secure and free from corrosion or damage.
  • Cable Management: Ensure cables remain neatly tied and do not get pinched or tangled in the recliner's moving parts.
  • Lubrication: The linear rail mechanism is generally self-lubricating. Do not apply additional lubricants unless specifically instructed by the manufacturer.

Troubleshooting

If your recliner motor is not functioning as expected, consider the following troubleshooting steps:

ProblemPossible CauseSolution
Motor does not operate.No power, faulty switch/remote, or motor connection issue.
  • Ensure the recliner is plugged into a working power outlet.
  • Check the power transformer connection (2-pin flat round) and the hand control plug connection (5-pin) for secure fit.
  • Test the switch/remote with another compatible device if possible, or inspect for visible damage.
Motor operates intermittently or with difficulty.Loose connection, obstruction, or motor strain.
  • Verify all connections are tight.
  • Check for any objects obstructing the recliner's mechanism or the motor's movement.
  • Ensure the recliner is not overloaded beyond its maximum weight capacity (120 kg).
Motor makes unusual noises.Mechanical interference or internal motor issue.
  • Inspect the linear rail and mounting points for any loose parts or debris.
